NATO’s Trident Juncture Exercise as a Deterrence Signal to Russia

I have a new article examining the impact of the Trident Juncture NATO exercise currently ongoing in Norway, published by the Kennedy School’s Russia Matters project.

This week, NATO forces are engaged in the largest military exercise the alliance has organized since the end of the Cold War and the first major Western exercise in decades to take place in the Arctic region. To be held in Norway through Nov. 23, the Trident Juncture exercise is designed to improve NATO’s ability to defend member states and to strengthen the alliance’s credibility as a deterrent force against potential aggression. While the scenario does not mention any particular adversaries, the exercise is clearly aimed at bolstering NATO defenses against Russia in the Nordic region. While the political impact will be minor by comparison to any potential permanent troop deployments, the military lessons gleaned by the exercise’s participants promise to be significant.

The exercise marks NATO’s third time holding the biennial Trident Juncture and differs from the previous two iterations in both size and focus. To begin with, it involves personnel from all 29 NATO members—a first—plus close partners Finland and Sweden. This in itself is significant: While the two Nordic states have regularly participated in NATO exercises in recent years and have invited NATO forces to take part in exercises on their soil, their participation in as large and politically prominent an Article 5 exercise as Trident Juncture highlights how far both have gone since their political decisions to enhance defense cooperation with NATO. The 2018 exercise is not only much bigger than the 2014 and 2016 iterations, which also focused on preparing NATO’s rapid reaction forces to counter Russian aggression, but differs significantly in its primary focus on field exercises instead of command post exercises.

There are 50,000 total participants, including 20,000 from the ground forces, 24,000 from naval and marine infantry forces, 3,000 from air forces, 1000 logistics specialists and 1300 command personnel. The United States has provided the largest contingent, including the Harry Truman Carrier Strike Group, the Iwo Jima Marine Expeditionary Strike Group and over 18,000 troops. Preparations, including deployment of forces to the exercise area, began in August. The active phase of the field exercise began on Oct. 25 and will continue through Nov. 7, to be followed by a command post exercise in mid-November.
